Range of Motion for an AR500:

Question:

What is the maximum angle that a remote ballast AR500 head can turn, both vertically and horizontally?

Answer:

If the Remote Head is pole-mounted, there is no restriction of the range of motion. If the unit is attached directly to a flat surface, such as a wall, the range of motion is reduced to 60 degrees of upward tilt and 65 degrees of downward tilt.

EPA (Effective Projected Area) of the AR500:

The EPA (Effective Projected Area) of the AR500 fixture is 3.4 Sq Ft for Remote Head units. The Effective Projected Area (EPA) is the exposed surface area of a fixture multiplied by a shape factor which varies depending on the shape of the fixture.
